Abstract
In an embodiment, a system on a chip includes: a single core to execute a legacy instruction set, the single core configured to enter a system management mode (SMM) to provide a trusted execution environment to perform at least one secure operation; and a memory controller coupled to the single core, the memory controller to interface with a system memory, where a portion of the system memory comprises a secure memory for the SMM, and the single core is to authenticate and execute a boot firmware, and pass control to the SMM to obtain a key pair from a protected storage and store the key pair in the secure memory. Other embodiments are described and claimed.
